I wonder if these folks would take this same attitude to other medical treatments. Sometimes people get misdiagnosed and receive the wrong treatment. Yes, it's unfortunate. No, people shouldn't be made to feel ashamed for being misdiagnosed and receiving incorrect treatment. It doesn't mean the treatment itself is wrong for everyone. If someone were misdiagnosed with diabetes and given insulin, that would end rather badly, but the problem was the misdiagnosis. In the meantime there are diabetics out there who need insulin.
They're willfully ignorant, all these people saying "they should be receiving psychiatric care!" Yeah, the thing is, the actual mental health professionals - the ones who've studied this condition for decades rather than basing everything on a knee-jerk reaction from ignorance - have reached a consensus that transition is the only effective treatment for this condition. "Reparative therapy" has been methodically proven not to be worth a crap. Ta-dah. Fanfare. Confetti.
